WASHING- MACHINE -slipncat'ion'ma February 16,19. semina. 9,6.

The present invention relates to washing machines and has for its objectto provide a device of this character which embodies novel i features ofconstruction, whereby the clothes receiving drum or basket' is mountedin such a ymanner that it can either be swung up4` wardly into anupright position and`rapidly rotated about a vertical axistocentrifugally 'expel moisture from the contents thereof, or swungdownwardly tol permit of the clothes being acted upon by a Huid in a.tub or compartment.

Among the objects of the invention are to provide a washing machine ofthis character which admits of the clothes receiving druml or basketbeing readily moved into either a washing position or-a' drying positionand which provides for spinning the drum at a high rate of speed when itis in an upright -position and oscillating it at acomparatively lowspeed when it is swung downwardly into a tub compartment. f

The invention also contemplates a mounting of the drum which enablesitto have a vieldable universal swaying movement when Y it is held in anupright position. This permits the drum to'bear down upon one side orthe other when the load is being placed there? in, according to thedisposition of the weight 3o of the material, and the operator isthereby enabled to distribute the clothes within the drum so as tosubstantially balance the same. The yieldable universal swaying movementof the drum also enables the drum, when driven at a high'rate of speed,to rotate and gyrate about its true center of gravity. I The term truecenter of gravity as used in this application refers to the center ofsupport of the drum at the yi eldable connection between 40 the drum andshaft, on which the drum can Vsway when unevenly loaded, and about whichthe drum can oscillate and gyrate during'rotation of the drum, sothat-the drum may balance itself during. the drying operation,

thereby' reducing vibration to a minimum and relieving theshaft andbearings of excessive strains. -By thus mount-ing the drum so that it ispermitted to have a yieldable universal swaying movement the machine isenabled to t perform its orifices without shocks and jars andunnecessary wear upon the journals and bearings. v v

The invention also' contemplates the provision of a construction inwhichthe clothes or fabrics being treated can .be washed and rinsed orwashed, rinsed and blued without being removed from the drum until afterthe' several operations have been completed.

While certain forms and embodiments of .the invention have been shownand described in detail for illustrative purposes, it willbe understoodthat 'many modifications andV l changes can be made in the details ofconstruction without departing from the spirit of thev invention. ,65The construction of the drum, and features of the drive for the drumareclaimed in application 47,205 filed by me July 3l, 1925.

lorresponding and like parts are referred to 1n the followingdescription and ,indicated on all ofthe views of the drawings by likethe bottom of the drum and the drum shaft referencecharacters.

Referring toFigures 1 and 2 of the draw- 1ngs,the.numeral 1 designates atub which is supported 1n an elevated position by the legs 2 and whichhas the lower portion thereof subdivlded by. a transverse' partitionSinto two separate compartments A and B. iThese compartments are adaptedto contain dil'er-l ent iluidswith which the clothes or fabrics are tobe treated. For illustrative .purposes it may be considered that thecompartment A containsv a' cleansing fluid such as soapy water, while"the compartment B ,contains rinsing water. A chamber C is arranged underthe compartments A andB and contains the gearing .which is employed forrotating the drive shaft to'actuate the drum in the required manner.

A clothes receiving drum 4 has perforated sidewalls and is mounted upona drum shaft u 5 whichex'tends throughthe axis thereof. of the drum isprovided at the central'pcrtion'fthereof with a raised portion rovides asubstantially joint packing washers 7 of rubber or the hke are appliedto the drum shaft and held ti htly against the upper and lower faces othe raised portion of the drum bottom by means of nuts v8 which arethreaded pn the shaft.

-The edges of the drum bottommay have de- `11 which is adapted to enteran opening inthe upper edge of the drum, and at the opposlte sidethereof with a sliding latch 12'1which'is adapted to lockfthe cover onthe drum. The edges of the.cover may also be provided with notches 14which interlockwith corresponding projections on the tub so"th`at thecover may be utilized as a meansfor obtaining'a driving connectionbetween the'shaft and the drum. The central-portion of the cover has apolygonal opening 15 which engages a corresponding polygonal portion 16*on the drum shaft, so that the cover is locked to rotate with the sha-ftwhen itis in position. It will be obvious that when the cover 10 isremoved from position the drited universal tilting movement about the yyieldable connection with the drum shaft which is provided by the rubberwasher members 7 However, when the cover 10 is placed shaft is: 'extendsthrough the @er of this' raised portionland in order to obtain a t' ht`is free to have a limin position itnot only provides a lockingconncction between the drum and the drum shaft, but also 4prevents'theyield/able joint between from functioning to permit a tilting movementof the drum relative to the drum shaft. When the drum is beingl spun inan upright position to centrifugally dry the clothes the tiltingmovement is desirable and the cover 10 is preferably removed. When thedrum is thus being spun in an uprightpos'ition the frictional engagementbetween the 4drum shaft and the drum at the yieldable joint is sutlcientto obtain a driving connection between the arts, because there is nosuccessive elevatlng and dropping vofthe contents of the drum by theaction of the baie platesy 29.' When the'drumis swung downwardly -intoone of the compartmentsthe cover-10 is placed inv osition to hold thecontents ofthe drum in p ace andlock the drum against any tiltingmovement relative to the drum shaft.

In thelowered position of the drum the cover is'also vdesirable toAprovide a locking connection between the-drum and the 'drum shaft,because the baiiie plates'29 then act to successively elevate and dropthe clothes a's 'the drum revolves, 'thereby placing a greater TheVlower end of thedrum Vshaft extends downwardly below the bottom of thedrum and has a semi-spherical friction head ap. plied thereto. When thedrum is in an upright position the rounded end ofthe head fits in adepression 17 in the top of a' driv-` ing head 18 which Vis applied' tothe upper end of a substantially vertical drive shaft 19, said shaftbeing j ournaled in a bearing sleeve 2O which is arranged at the middleportion of the partition 3. A polygonal stud 21l projects from thefriction head 16 of the drum shaft and is adapted to enter a polygonalpocket 22 in the base of the depression 17 in the driving head. As shownclearly by Figure 8 the stud 21 has a cross section which is somewhatless than the pocket 22, so that the stud can have a limited amount ofplay within the pocket, although the polygonal base ofthe stud andpocket produces an interlocln'ng connection between the drive shaft anddrum shaft so that the two shafts must rotate in unison. The play of thestud 21 in the'depression 17 as the drum tilts to one'- side or theother side. This tilting of the 'drum is of assistance to the operatorin distributing the clothes or fabric within the drum so as to obtain aneven loading thereof, and also enables the-axis of the drum and load totend to assume a vertical position when i being rapidly rotated to'expelmoisture from the contents thereof by centrifugal force, even though thefloor upon which the washing machine rests is not level and the driveshaft is not `exactly vertical. This would serve to reduce the vibrationand relieve the bearings of excessive strain. y

The base of the pocket 22is shown as provided with an elastic buffermember 23 of rubber or like material which engages the lower end of thestud 21 and tendsto position the stud at the center of the pocket.However, the buifer is elastic and will yield to any force sufcient topartially compress the same.. Unnecessary looseness and play of the drumis thereby preventedalthough the drum is not held-rigidly inpositionf'and can have av limited swaying movement in any direction.

-. A bearing member 24 is loosely applied to ythe drum shaft 5andengages a guide-way 25 in a spider 26 which is arranged Vover thedriving head 18, vsaid spider'beingsupported rigidly in position. Whenit ijs desire-d Vto swing the drum' downwardly to subject the contentsthereof to the action of the fluid in one of the tub compartments, thedrum is first lifted a suiiicient amount to disengage the stud 21 fromthe pocket 22, after which the drum is swung to one side and loweredinto the desired compartment. rlhe end of the drum shaft 5 then engagesa notched bearing 27 at the side ,of the tub so that'the outer end ofthe drum is properly supported and the periphery of the friction head 16then rests upon the upper surface of the driving head 18, so that thetwo members 16 and 18 provide a friction gear connection between thedrive shaftand the drum shaft. The

drum shaft is provided with a stop collar 28 which loosely engages thebearing member 24' and cooperates therewith to prevent longitudinalmovement of the drum shaft toward the center of the tub. The drum isthus properly supported in a lowered position with the axis thereofsubstantially horizontal, andl a driving connection is provided betweenthe drum .and the drive shaft.

When the drum is swung downwardly into a horizontal position it ispartially submerged in the fluid so that the clothes or fabrics withinthe drum will be acted upon by the fluid when the drum is oscillated inthe usual man.- ner. In order to facilitate this action the interior ofthe drum is provided at the periphery thereof with the balile `plates29. The spider 26 may be supported in any suitable manner and is shownas'secured to a frame or cage 30 which is mounted upon the upper end ofthe bearing sleeve 20.

The spider or guide member 26 which is shownby Figure 6 has a guide-way25 extending diametrically across the same and is intended to be usedwith a tubhaving two compartments,fsuch as that illustrated by Figures 1and 2. A modified form of spiderA tion and is provided at the lower endthereofwith a sliding pinion 31 which is keyed thereon. TheA pinion isprovided with an arm 31a projecting into the central Vopening thereofand sliding within a longitudinal slot 32 loo in the drive shaft. Thisarm 31a is connected i to a gear shifting rod 33 whichextends upwardlythrough the tubular shaft and is engaged by the stud 21 .of the frictionhead 16 when the drum is in an upright position. The sliding p'inion 31is then pushed downwardly against the action of a coil spring 34 whichsurrounds the drive shaft and is interposedbetween the pinion and acollar 35 on the drive shaft; When the pinion 31 is thus moveddownwardly it meshes with a gear 36 andwhen the pinion is permitted tomove upwardly it disengages itself from the gear 36 and' engages atoothed segment 37. The

gear wheel 36 meshes with an intermediate i imparted thereto, while ythegear wheel 36 is rotated continuously in one direction. When the drum 4is swung upwardly with the axis thereof in a vertical position the gearshifting rod 33 is -forced downwardly to slide the pinion 31 intoengagement with the gear wheel 36 and the ratio of the gearing is suchthat the shaft-and drum will then be rotated at a high lrate of speed,thereby expelling any water from the clothes or fabric within the drumby centrifugal force. When the drum is swung downwardly to bring theaxis thereof into a horizontal position, as indicated by dotted lines onFigure 2, the gear shifting rod 33 is permitted to move upwardly and thespring 34 slides the pinion 31 into engagement with the toothedsegment37. The drum is then oscillated back and forth at a much slower rate ofspeed. The shifting of the gears may, of course, be accomplished in anysuitable manner and the exact mechanism for accomplishing this resultisnotmaterial to the present invention. I' l ,A drain plate 46 isarranged within the tuband has one diameter which is greater than the.diameter of the tub, so that it rests i on the sides'of the tub in aninclined position, where it is held by the partition 3 and frame 30,about which it is adapted to be rotated over either one of the-compartments A or B. `A handle 47 extends upwardly from a marginalportion of lthe drain plate and the drain -plate is preferably4 inclinedso that any liquid falling Aupon the same will be drained into theuncovered compartment. The fluid expelled from the clothes or fabricswhile the latter are being centrifugally dried will thus be conveyedback into the tub compartment from-which it was originally taken.

A modified form of the Ainvention is shown by Figure 10, in which thedrum is adapted to be mounted upon and driven by any selected one of aplurality of shafts. The drive shaft 48 is journaled in a bearing 49which has an enlargement 50 at the upper end thereof. A cage 51 extendsover and around the enlargementv50 and is supported ona plate 52secured'to the bearing. The cage is provided at the top thereof with abearing 53 .receiving the drive shaft 48, and the opposite sides thereofwith auxiliary bearings 54l receiving 'inclined shafts 55. The innerends of these lateral or inclined shafts 55 are journaledin all of theshafts arev bearings formed in the enlargement 50 of the i main bearingso'that thelateral shafts are sturdily mounted and can carry a heavyloa'd. y

The inner ends of the lateral shaftsare provided with gear wheels 56which mesh l.with a pinion 57 on the main drive shaft 48-'so that gearedtogether to rotate in unison.

vThe upper end of the drive shaft 48 has a polygonal cross section andis loosely received in a socket 58 formed in the bottom-of a disc 59which normallyhas ,the lower face there. of slightly spaced from a'stopflangel 60 on the drive' shaft. The top of the` disc 59 is formed witha'polygonal stud 61 Iwhich is detachably engaged by a socket member 62 atthe lower end of a drum shaftv5 which is rigid with the drum. The'drum'is mounted upon the disc 59 when it is in an "upright position-and isintended to be rapidlyrotated to centrifugally dry the clothes, andowing p the socket 62 is then brought into engagement with the polygonalouter end of one of the lateral shafts 55. The drum then assumes one ofthe dotted line positions indicated by Figure 10, and the arrangementwithin the tub may be such that the drum is then partially submerged inthe fluid with which'the clothes are to be treated. Any suitablev meansmaybe lprovided for operating the drive shaft in the proper manner whenthe drum is in the different positions. When the drum is elevated withthe axis thereof substantially vertical, it will be driven at a highrate of speed to centrifugally dry the contents thereof, while when thedrum is in one of the dotted line positions it is preferably voperatedat a much lower rate of speed and revolves alternately in reversedirections. Any suitable means may be provided for imparting thenecessary motion to the drive shaft.

A different modification is illustrated by Figure 11, in which theupright drive shaft is designated by the numeral 63, said shaft beingjournaled in a suitable bearing 64. The drive shaft extends upwardlyabove the bearing and terminates in-a substantially semi- 4sphericalfriction head 65 which has a polygonal socket 66 in the top thereof. Thedrum 4 has a cone shaped raised portion 67 in the Y and then tiltedlaterally to bring the friction Y Yeo lis adapted tobe received thesocket 66 the purpose of subjecting the contents thereof.

to the action of a fluid, the drum is lifted to. disengage the stud 68from the socket 66 head into engagement with the concave wall 70 of thefriction ring 69. The outer face lof the friction gear ring then restsagainst a friction pinion 71 which is rigid with the drive shaft 63. Thecover of the drum is provided with a stub shaft 72 which engages abearing 73 at one side of the tub and serves both to support'the outerend of the tub and to prevent the tub from swinging around on the driveshaft as an axis. The drive shaft can be suitably rotated to impart thedesired movement to the drum, the friction head and friction pinionengaging op posite sides of the friction gear ring 69, so that a drivingconnection is obtained between the shaft and the drum.

A further modification is shown by'Figure 12, in which thev up'per e'ndof the tubular shaft 74 is provided with a cup shaped head 75 which hasa pocket 76 inthe bottom thereof.V The drum 4 has a raised portion 77 atthe center of the bottom thereof and is provided with a drum shaft 78which extends downwardly below the bottom of theV drum and is disposedat the axis thereof. The shaft 78 Vis rigidly connected to the drum andan internal web 7 9 may extend across the hollow interior of the raisedportion 7 and' engage the shaft for assistance in obtaining a rigidconnection between the shaft andthe drum. The lower end of the drumshaft terminates in a friction ballv80 which is received within thepocket 76 in the bottom of the depression in the driving head 75 whenthe drum is in an upright position. Just above the friction ball 80 thedrum shaft is provided with an enlarged portion 81 which is engaged bya. louder ring 82 of rubber or similar elastic material which-is`arranged at the upper end of the pocket or recess 76. The lower end ofthe drum shaft is removably received within the pocket when the drum issupported in an pright position with the axis thereof disi 'ip-[olsedvertically and the ball 80 then has a `ctional engagement with the wallsof thepocket while the enlarged portion 81 of the Vsh ft-is engaged bythe bud/,er ring 82 to hold.

the drumY resiliently in position; VThe drum shaft thus has a frictionalengagement with the drive shaft'so that the drum can be driven fromthedrive shaft, although the drum can rotate independently of the driveshaft when starting or stopping so that sudden shocksand jars areavoided. The rubber buffer ring 82 holds the drum shaft resiliently inan Aupright position, although the drum shaft has a limited universalmovement and can be tilted in any direction by compressing the bufferring. If the machine is not level and the driving shaft is slightly outof a vertical position the buffer ring 82 will yield and permit the drumshaft to assume a'vertical position when the drum is being rapidlyrotated to centrifugally expel moisture from the contentsl thereof.

A friction ring 83 is arranged within the mouth of the cup shaped drivehead 75 land this ring has upper and lower concave friction surfaces83a. is formed upon' the drum shaft 78 and the "distance between the twofriction balls 84 and 80 is equal to the diameter of the friction ring83. When it is desired to oscillate 'the drum with thek axis thereofswung downwardly int-o a substantially horizontal position, the drum islifted to 'disengaged the lower end of the drum shaft from the pocket 76and then swung downwardly into the position indicated by dotted lines onFigure 12. The

friction ball- 80 then engages the lower concave friction surface 83a ofthe friction ring 83, while the other friction ball 84 of the drum shaft.engages the upper concave friction surface of the friction ring at adiametrically opposite point on the friction ring.

-The drum'is thus supportedbythe engagement of the friction balls on the'drumshaft with the upper and lower surfaces of the friction ring 83.The cover of the drum may be provided with a stub shaft 85 which engagesa notched bearing 86 on the side of the tub to prevent the drum fromrotating bodily around the upright drive shaft. The universal engagementbetween the friction ring A second friction ball 84 y 83 and the twofriction balls 8O and 84 of the drum shaft will serve to importrotarymotion from the head 75 of the drive shaft to the drum shaft and drum,and the mechanism for driving the main shaft 74 may be such that theshaft can be spun at a high rate of speed when the drum is swungupwardly and the contents thereof will be centrifugally dried, andoscillated at a compararA tively low rate of speed when the drum isswung downwardly and partially submerged in the liuid contents of a tubcompartment. l

`The gearing mayjbe controlled by a. gear shifting rod 33 which isarranged within the ,tubular main shaft, just as described in connectionwith the embodimentl of the lnven tion shown by Fig. 2. y

Referring again to the construction shown by Figs. .2 and the cover 10may be removed from the drum .when the drum 1s being spunlin` an uprightthe contents Therubber position to expel moisture .from thereof bycentrifugal force.

12:5` i 5, it may 'be explained that washerv members 7 -then provide' aresilient connection between the drum and the drum shaft so that the'drum can have a limitedl tilting movement about the drum shaft andassume -a balanced position thereon. The drum -can thus have a limitedtilting movement with respect to the drum shaft, and

the drumshaft, as previously explained, has a limited tilting movementwith respect to the main drive shaft, so that thedrum can adjust itselfwhen'driven at a high rate of s eed to bring the center of gravity o fthe um and load over the vertical axis, and

- thereby reduce friction and strains to a minimum. The baiiie platesv29, which are arranged around the inside peri hery of the drum, arepreferably wide at t e topof the drum and taperor 'decrease in widthtoward the bottom ofthe drum so as to minimize the possibility of theclothes or fabric within the drum being torn when the drum is rapidlyrotated to centrifugally dry the same. As

indicated by Fig. l, the interior partition 3 of the tub is preferablyhollow so as to provide an air space or vacuum between the spaced sidewalls thereof. This enables the different compartments of the tub tocontain fluids at 'dierent temperatures without the heat from the fluidin one of the compartments being quickly conducted through the partitioninto'the fluid in another compartment. When washing clothes itisfrequentv ly desirable to have cold water in one tub compartment andhotswater 'in another tub compartment and this is ossible where the,partition 3 has a hollow ormation so as to provide a dead air space ora vacuum space.

When washing clothes or fabrics in a. rotating drum there is a tendencyfor the clothes or fabrics to roll up into a ball or balls if the it isnot necessary that the drum alternate in its direction of rotation toprevent the rolling up of the clothes, since the substantiallytriangular baille plates 29 pick up the clothes an'd carry them out ofthe water, the clothes having a tendency to slide toward the narrow endof the baiile-plates as they are being carried up, due to theinclination of the drum. After being carried u by the bailie plates theclothes slide oi an drop on the conical projection in the center of thedrum, and they then slide over the walls of the cone and drop upon thelower portion of the drum. The triangular bale plates and conicalprojection within the drum thus coopcrate with each other to cause theclothes to slide against the respective members, hitting the cone firstand then the liquid after being dropped from the top of the drum, thushitting twice each time they are carried up and dropped and slidinginstead of rolling oi the obstruction. This tends to prevent the clothesor fabrics from rolling up into a ball or balls, so that if it isdesirable a drum constructed in. this manner may be rotated continuouslyin one direction while the clothes are being subjected to the action ofthe cleansing fluid.
